Dry Bottom Ash removal system eliminates the need of water for transporting bottom ash from below the furnace.


Dry Bottom Ash
Handling System

Macawber Beekay introduces DryAshTech Conveyor for dry handling of Bottom Ash below the boiler furnace. The DryAshTech an innovative solution used as a Dry Ash Conveyor for cooling and conveying of combustion residues of fossil fired power stations and waste incineration plants.

Highly reliable and robust DryAshTech is setting standards and fulfils the highest requirements in terms of environmental protection and conservation of resources due to its water-free operation. Due to only minor rolling friction on the supporting rollers and the other components, located protected from the material to be conveyed, the DryAshTech presents considerable key advantages compared to its competitors.

From the outside removable, lifetime lubricated supporting rollers in combination with impact tables, able to absorb single weights of more than 5.0 t, make the DryAshTech to a guarantor for a trouble-free plant operation.

Benefits of DryAshTech:

  • This is a fully enclosed system
  • Water usage for quenching of hot BA is eliminated and hence there is no requirement of Bottom Ash Cooling Water system & effluent water treatment system
  • Eliminates the requirement of Ash Pond hence no impact on ground water quality
  • Compliance with environmental protection regulations
  • There are reduction of thermal energy losses & unburned carbon and hence improved boiler efficiency
  • Maintenance costs are low.
  • Usable bottom ash quality
  • Easy to transport
